The present invention relates to a Cffie fan operation display device. In a conventional heat dissipation device, since a fan attached to Cffie stops operating and the computer stays inside the computer body even if the computer malfunctions or goes down, it is necessary to remove the body directly. Until it was determined that the failure by the fan, and touched other parts may cause the secondary failure, there was a problem that takes a long time to find the cause. Therefore, the present invention detects a current value consumed by the fan and displays it when an overcurrent flows, and cuts off the current flowing to the fan, thereby preventing malfunction and failure of the CAPI oil in advance.
